Abstract: PURPOSE: To provide the unit structure of a semiconductor element and a cooler which is arranged to be easy to be incorporated into a device. CONSTITUTION: Stack units whose key parts are semiconductor elements la and 18 are welded and fixed on both sides of a fixing board 4. For the cord of each part, A and B, which show the parts belong to left side and right side, respectively, are added. Talking to the left side, an insulating spacer 3A, a conductor-cooler 2A, a semiconductor element 1A, a cooler 2A, and a insulating spacer 3A are stacked coaxially in this order on the left flank of the fixing board 4. Two pieces of poles 5A are erected, and a plate spring 6A laid between the left ends adds pressure to the stacked unit, according to the degree of fastening by a nut 7A at the center.  This pressure is set to a recommended value for the thermally and electrically well conductivity between the semiconductor element 1A and each cooler 2A on both sides for the first reason and for maintenance of mechanical strength of the semiconductor element 1A for the second reason. In short, the pressure to the right stacked unit and that on the left side are generally different.

Title: Filter cloth for belt press type dehydrator
Inventor: ARAKOMO HIROAKI
IPC: B01D33/04
Filed: 1988-06-01
Abstract: PURPOSE:To permanently keep antistaining effect and release effect, by constituting at least the warp yarn of filter cloth of a synthetic resin monofilament containing a fluororesin. CONSTITUTION:A synthetic resin monofilament obtained by mixing 3-7wt.% of a fluororesin with a polyester resin and subjecting the resulting mixture to melt spinning is arranged as the warp yarn 1 constituting the greater part of a squeezing surface. After a usual synthetic resin monofilament is used as weft yarn 2 to be woven into a herringbone pattern along with the warp yarn 1, the obtained fabric is subjected to heat treatment and joint processing to form filter cloth 3 for a belt press type dehydrator. When the fluororesin- containing monofilament is also arranged as the weft yarn, release effect is further enhanced. By this method, since antistaining properties and releasability are enhanced from the early stage to the terminal in use, this filter cloth largely contributes to the enhancement of the dehydration property or productivity of sludge of the belt press type dehydrator.

Filed: 1980-09-30
Abstract: PURPOSE:To detect the optical input level, by fixing the bias voltage of an avalanche photodiode (APD) when an electric output level gets out of the specified range. CONSTITUTION:An electric output from an APD1 is amplified by amplifiers 2 and 3, and pilot signal components are removed by an LPF6 and outputted through a terminal OUT. In this case, pilot signals are extracted in automatic gain control circuit 4 by using a BPF41 and they control continuity of transistor 7 in accordance with a pilot signal level through comparison circuit 44 and also control the bias voltage of the APD1. When the pilot signal level is lowered less than a specified value, the output of a comparison circuit 45 is reversed and a contact rl of relay 47 is opened. Therefore, the bias of the APD1 is also fixed. Under this condition, when the output of the amplifier 2 is monitored by using a monitor circuit 5, the optical signal level can be known.
